Series B0 Inverted Bucket Traps The Series B0 Inverted Bucket Traps are designed for a wide range of industrial applications including unit heaters, laundry and process equipment and steam line drip traps.
These cast iron inverted bucket traps operate efficiently for long periods of time to add solid energy savings by lowering replacement and labor costs. They are fully repairable for even bigger maintenance savings.
Typical Applications:
– Drip traps in steam lines – Tracer lines – Process equipment – Steam cookers – Steam kettles – Steam heated vats – Pressing machinery – Unit heaters – Commercial dishwashing
Features: – Available in sizes 1/2" and 3/4" NPT – Pressure ratings 20, 80, 125 and 150 psig
(1.4, 5.5, 8.6, and 10.3 bar) – Removable covers for easy in-line service – Stainless steel internal components – Resistant to moderate water hammer – Optional built-in strainer to reduce the number of
piping connections – Maximum capacities to 690 lbs/hr (313 kg/hr) – Maximum temperature 406ºF (208ºC) – Maximum allowable pressure (vessel design)
250 psig (17.3 bar) – Maximum operating pressure 150 psig (10.3 bar)
